England StPaul was provided by Samad Ahmadi and Gwendy van Schooten, and converted to XHSTT by Gerhard Post. It is data from St. Paul Catholic School in Leicester from the year 2005-2006. The original idea was to have a real English dataset with teacher assignments as part of the problem. To be used in the existing (Dutch) software it was Dutchified by assigning all teachers to the events beforehand. These assignments were done based on the schedule produced by the school. This solution shows that it should be possible to assign all the events to the first 5 time slots of days, but till now no feasible solution was found.
A summary of the data can be found in the following table:

The following constraints are present:
- Scheduling constraints: AssignResourceConstraint and AssignTimeConstraint.
- Event constraints: SpreadEventsConstraint and LinkEventsConstraint.
- Resource constraints: AvoidClashesConstraint, AvoidUnavailableTimesConstraint, and LimitIdleTimesConstraint.
